【摘要】：在运输服务供应链中,由于需求的不确定性,不仅托运人的托运承诺时间对运输服务供应链的决策产生影响,而且随着需求信息的不断更新,托运人对需求信息的掌握程度也对运输服务供应链的决策产生影响。基于外部定价和承运人定价,考虑了不同承诺时间内需求信息更新的情况,建立了运输服务供应链优化决策模型。通过模型计算结果发现:无论是外部确定运价还是承运人确定运价,承运人总希望提早承诺,而托运人总是希望延迟承诺;在外部确定运价情形下,提早承诺和延迟承诺对运输服务供应链是否有利,则与运价有关,在运价转低时,延迟承诺对运输服务供应链有利,而运价较高,则提早承诺对其有利,在承运人确定运价情形下,延迟承诺情形下的运输服务供应链收益大于提早承诺时的运输服务供应链的收益。
[Abstract]:In the transport service supply chain, due to the uncertainty of demand, not only does the shipper's shipping commitment time have an impact on the decision of the transport service supply chain, but also with the continuous updating of the demand information, Shippers' mastery of demand information also has an impact on the decision-making of the transport service supply chain. Based on external pricing and carrier pricing, the optimal decision model of transport service supply chain is established by considering the update of information required within different commitment time. The results of model calculation show that the carrier always wants to make an early commitment, while the shipper always wants to delay the commitment, no matter whether it is the external fixed freight rate or the carrier determines the freight rate; in the case of external fixed freight rate, the carrier always wants to delay the commitment. Whether or not early and delayed commitments are beneficial to the transport services supply chain is related to the freight rate. When the freight rate is lower, the delay commitment is beneficial to the transport services supply chain, while the higher the freight rate, the earlier commitment is beneficial to the transport services supply chain. When the carrier determines the freight rate, the revenue of the transport service supply chain in the case of delay commitment is greater than that in the transport service supply chain with early commitment.
